SPECIFICATION forming part of Letters Patent No. 549,646, dated November 12, 1895.

Application filed July 6, 1895. $erial No. 555,138. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM J. LAPWORTH,

a citizen of the United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented a new and useful Adjustable Boxing for a Vehicle-Wheel, of which the following is a specification.

My invention relates to the improvement over the old non-adjustable box; and the objects of myimprovements are, first, to provide an adjustable boxing that will at all times be as firm as a solid box; second, one that will keep the Wheel firm and true and have a much longer life than the solid box; third, one that can be adjusted by any person; I attain these objects by methods shown in the accompanying drawings, in which- Figure 1 is a side elevation of the solid box with the upper right-hand corner broken away, so as to show the outside of box B B. m is the metallic distance pieces or liners; b, wedge-nut for setting up the boxing; 0, looknut to secure wedge-nut b; 'i, key-seat in boxing B. a is a key on box A to prevent boxing B B from revolving. E is a nut on axle.

Fig. 2 is a longitudinal section of Fig. 1. A A is the solid box; B B, the adjustable boxing; a a, keys; 71 '5, key-seats; ff, angle of wedge on boxing B B; h, angle on wedgenut Z); k, threads; dd,'wrench-slots; c,locknut; e e, wrench-slots. C is the axle; D,

collar; Z, leather washer; E, nut on end of axle.

Fig. 3 is a perspective view of wedge-nut 12, broken away to show angle of wedge; 01 d, wrench-slots; k, threads.

Fig. 4c is the wrench for adjusting nuts I) and c.

Fig. 5 is a transverse section of Fig. 1 on line 00 as. a a, are the fixed keys; A, solid box; B B, adjustable boxing; 'm on, metallic liners; G, axle.

To adjust boxing, take out lock-nut c, slack back wedge-nut I), reduce liners mm to proper thickness, set up wedge-nut b, and lock with nut c, which will leave the boxing solid and firm, as when new.

What I claim as my invention, a'hd desire to securebyLetters Patent, is

In a boxing for a vehicle wheel, the combination, with the box A provided with a conical portion at one end, a screw-threaded chamber at the other end, and a cylindrical middle portion provided with keys; of two half bearings B B for the axle, provided with conical ends and a cylindrical middle portionhaving slots engaging with the said keys, removable liners m interposed between the said half bearings, and a nut screwed into the said chamber and provided with a conical portion encircling one end of the said half bearings, and operating when screwed up to tighten the said half bearings upon the said liners, thereby forming a substantially solid cylindrical bearing for the axle, substantially as set forth.
